Subject: [PATCH AUTOSEL 5.7 046/274] drm: rcar-du: Set primary plane zpos immutably at initializing
Date: Mon,  8 Jun 2020 19:02:19 -0400	[thread overview]
Message-ID: <20200608230607.3361041-46-sashal@kernel.org> (raw)
In-Reply-To: <20200608230607.3361041-1-sashal@kernel.org>

From: Tomohito Esaki <etom@igel.co.jp>

[ Upstream commit 7982471d01aac33994276bf567c8f1f3a137648a ]

According to drm_plane_create_zpos_property() function documentation,
all planes zpos range should be set if zpos property is supported.
However, the rcar-du driver didn't set primary plane zpos range. Since
the primary plane's zpos is fixed, set it immutably.
